Bit 6: Receive HDB3 Enable (RHDB3)
Bit 5: Receive Signaling Mode Select (RSIGM)
Bit 4: Receive G.802 Enable (RG802). See
Bit 3: Receive CRC-4 Enable (RCRC4)
Bit 2: Frame Resync Criteria (FRC)
Bit 1: Sync Enable (SYNCE)
Bit 0: Resynchronize (RESYNC). When toggled from low to high, a resynchronization of the receive-side framer is
initiated. Must be cleared and set again for a subsequent resync.
0 = HDB3 disabled.
1 = HDB3 enabled (decoded per O.162).
0 = CAS signaling mode.
1 = CCS signaling mode.
0 = Do not force RCHBLKn high during bit 1 of time slot 26.
1 = Force RCHBLKn high during bit 1 of time slot 26.
0 = CRC-4 disabled.
1 = CRC-4 enabled.
0 = Resync if FAS received in error three consecutive times.
1 = Resync if FAS or bit 2 of non-FAS is received in error three consecutive times.
